Mahle MS BBC Elite Sportsman Drag Series Piston Set - 4.605in. Bore/15.6 CR/583ci/4.375in. Stroke

These Mahle Elite Sportsman Drag Series pistons are built for serious performance in Big Block Chevy engines, specifically for a 583 cubic inch displacement. They feature a 4.605-inch bore and are designed to work with a 4.375-inch stroke, creating a substantial 15.6:1 compression ratio with a 47.0cc combustion chamber volume. This setup is geared towards drag racing applications where maximum power output is the primary goal.

Crafted from 2618 aluminum alloy, these pistons are known for their strength and ability to handle high cylinder pressures and temperatures common in performance drag racing. The 1.060-inch radius dish helps achieve the high compression ratio while managing piston-to-valve clearance, a critical factor when building a high-performance engine. Each piston weighs in at 621 grams, a carefully considered weight for optimal balance and reciprocating assembly performance. The 0.990-inch wrist pin diameter is standard for many performance applications, ensuring compatibility with a wide range of connecting rods.

This set includes all the pistons needed for your Big Block Chevy build. It's important to note that these pistons are not CARB approved and cannot be shipped to California due to emissions regulations. Always consult your engine builder or Mahle's technical resources for specific installation guidelines and to ensure proper fitment with your cylinder heads and connecting rods for optimal performance and reliability.
